The length of the rose flowering depends on the season and climate. Generally speaking, the first crop in spring takes a long time, and the last crop before winter takes the longest time. It depends mainly on temperature. The higher the temperature, the shorter the flowering period; the lower the temperature, the longer the flowering period. This is a general rule. All petals hard, petals thick, flowering will be longer; all petals soft, petals thin, flowering will be shorter. Let's put it this way, the season and climate are suitable, and it is not uncommon for a long time to open for 10 days or 8 days; the season and climate are not suitable, and at most 1-2 days. Of course, people have subjective initiative, no matter how inappropriate the season, you can artificially add a reed curtain or sunshade net, or get under the eaves, tree shade, can also extend the flowering period.

How can roses bloom more?

1. Rose flowers are large and need more fertilizer, so it is advisable to apply more fertilizer and apply enough organic fertilizer before germination. For potted rose, should be in early spring to change the pot once, pot soil formula: (loam) 5:(rotting soil) 2:(decomposed dung) 2:(sandy soil) 1, and then add a small amount of cake, mix well. After every 10 to 15 days a topdressing. Topdressing available cake fertilizer plus phosphate retting system of liquid fertilizer on water irrigation, especially in May after full flower, should be timely fertilization to promote summer and autumn flowering.

3. Rose is in semi-dormant state above 33℃, and it is most conducive to growth when the average temperature is 20~25℃. Therefore, proper shading and multiple spraying should be carried out in summer. Cooling moisture, in the growing season, it is best to spray water once in the morning and afternoon to create a humid environment and promote the growth of flowers and leaves.

4. After flowering, the rose should be cut off below the third compound leaf under the flower to promote strong new branches and early bud flowering. Pruning techniques are: weak short branches first cut, high cut; strong branches after the cut, short cut, to promote weak suppression, promote its orderly flowering. Long branch pruning length should not exceed 1/2, avoid axillary bud germination delay. In addition, each crop should not be too many flowers, potted roses to 3~5 is appropriate, planted roses depending on the strength of the plant. The remaining flowers are too many nutrients too scattered, the flowers are small and affect the next crop of flowers.
